LOCK-STRIKE.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed November 11, 1914. Serial No. 871,490.

To atl whom it may concern Be it known that I, EDWARD A. MILLER, a citizen of the United States, residing at Ionia, in the county of Ionia and State of Michigan, have invented certain new and useful Improvements in Lock-Strikes, of

' which the following is a specification.

This invention relates to lock strikes, and

. belongs to that class of metal devices constructed to be secured in door frames, and against which the spring-bolt of the locks strike when the doors are closed.

The object of this invention is the production of a lock strike having parts of special formation and arrangement and believed to be particularly useful for the doors of automobile bodies and the like wherein sheet metal is employed as the external covering of a suitable frame.

This invention is specially constructed to engage the sheet metal plates as described hereinbelow.

The construction and arrangement of the parts of this invention are illustrated in the accompanying drawings, of which Figure 1 represents a horizontal section of a portion of the sides of an automobile body, and a portion of one of the doors to which this invention has been applied. Fig. 2 is a front view of this invention detached. Fig. 3 is a plan View of this invention, the plan being of that side of the base plate from which the inclined block projects. Fig. 4: is a rear View of this invention, and Fig. 5 is a cross-section upon the broken line a9w of Fig. 3.

Throughout the description and drawings the same letter is used to refer to the same part.

Considering the drawings, in Fig. 1 the letter A refers to the doorframe, and the letter B to a portion of a door having a lock with the spring bolt 6, all of customary construction and arrangement.

In this invention a block C, which has its outward side or face inclined as illustrated, projects from a base plate D.

In Fig. 3 countersunk screw holes E and e are shown, by which the plate D may be attached to the doorframe in the ordinary manner. The plate D is longer than the width of the block, and the ends having the screw holes project beyond the sides of the block. In Fig. 3, the base plate D is shown to have the rounded corners F and f. The

object of this is to do away with one hand operation in setting the lock strike in the wood. The lock pillar or doorframe can be rounted out with a rounting machine, and the plate D can be set in its seat Without making a hand operation to square out, as is commonly done. It will be noted that the block 0 is wider than the base plate D, and that the front edge or lip of the inclined face of the block projects somewhat beyond the front or corresponding side of the plate. In Figs. 2, 3, 4 and 5, it will be further observed that beneath the front edge of the block 0 and running lengthwise with respect to the plate D is a groove Gr next to the plate, and at right angles thereto are like grooves H and Th, partly separating the block from the plate. The grooves are cut in the block next to the plate for the insertion of the metal panel J. The broken lines in Fig. 3 indicate the shape and character of the recess out in the bent end portion of the panel J to engage the grooves Gr, H and it. As shown in Figs. 2 and 4, one side of each groove is flush with the surface of the plate, and is, in fact, a continuation of such surface.

In the application of this invention to the doorframe A or the like, the bent edge portion of the panel J is inserted in the grooves, and there is no need for solder to hold the panel securely. Furthermore, it makes a neat, smooth and sightly connection. It will be noticed in Fig. 1, that the front edge or lip of the inclined face of the block C extends to, and it may project slightly beyond the corner or bend in the panel J. When the lock bolt 6 strikes and rides to place, it cannot injure the corner of the panel. In the same way, when the door B is opened and the lock bolt 6 is coming out, the inclined face of the block C protects the angle of the panel.

Having now described this invention and explained the manner of its operation and application, what I claim is 1. A lock strike, comprising a base plate and a block projecting from the plate and having its outward side or face inclined, the said plate being longer than the width of the block, and the said block having a groove formed below its front edge next to the said plate and extending lengthwise with respect to the said plate, one side of the groove being flush with the surface of the plate.

2. A look strike, comprising a base plate and a block projecting from the plate and having its outward side or face inclined, the said plate being longer than the width of the block, the said inclined side being greater in width than the said base plate, and the said block having a groove formed below its front edge next to the said plate and extending lengthwise with respect tothe said plate, one side of the groove being flush with the surface of the plate.

A lock strike, comprising a base plate and a block projecting from the plate and having its outward side or face inclined, the

said plate being longer than the width of the block, therea'r of the said block being formed flush with the back of the said plate, the said block being greater in width than the said plate and the front edge of the block being constructed to project beyond the front edge of the said plate, and the said block having.

a groovefor ned below its front edgeneXt to the said plate and extending lengthwise with respect to the said plate, one side of the groove being flush with the surface of the plate.

at; A and a block projecting from the plate and having its outward side or face inclined, and the said block having grooves formed next to the said plate and partly separating the copies of this patent ma: be obtained for lock strike, comprising a base plate block from theplate, one side of each groove being flush with the surface of the plate.

5. A lock strike, comprising a base plate and a block projecting from the plate and having its outward side or face inclined, the

.said block being greater in width than the said' base plate, and the said block havinggrooves formed next to the said plate below the front edge of the block and on two sides of the block partly separating the block and plate, one side of each groove being flush with the surface of the plate.

6. A lock strike, comprising a base plate and a block projecting from the plate and having its outward side or face inclined, the

rear of the'said block being" formed flush I EDWARD A; MILLER, WVitnesses FRED M. Coon, MINNIE J ORDAN:
